Autopilot AP-105 when engaged controls rolls right at ground, in heading mode rolls right also when pitch up commanded.

All wiring check carried out ,VG.DG.ATTITUDE SELECT RELAY.INS.AMPLFIRE.MODECUPLERS,CONTOLE PNL SWAPED with good one,wiring check carried out no help.

Please advise.

Is the airplane parked at a level roll attitude?  I know the AN/AYW-1(V)1 will command roll input if the airplane isn't level.  However, if you're saying the a pitch input by itself commands a roll, then you have a real problem.  Haven't tried this with the FCS-105 though.

agree ,but in heading coupled should come to neutral and on pitch up should follow up/down not to roll right.

and one more input if we remove elevator servo plug no roll to right either engage or handing hold, obvious there cannot be any pitch control.

Sounds like it may be a shield problem at the common terminal board around FS617. You may be getting interference to the aileron servo from the elevator servo wiring. Otherwise, check shields at autopilot computer.
